First of all Merry Christmass !
Secondly thank you for this tutorial.
Thirdly I require some help with removing those pesky ads from my kindle 4NT.
I Have followed the steps in "kindle root access via usb networking" but I'm getting stuck after activating USBnet on the kindle. I change the IP as instructed but I cannot connect to the device. I have tried to ping it and 192.168.15.244 is not on the network. Also will doing this conflict with further updates from amazon ?

I've fixed the connection issue but cannot seem to be able to use custom screensavers... I cannot mntrootfs -rw because It says it's not found. I have tried mnroot -rw and completed the process to no avail. Everything worked fine but the screensavers didn't appear
Any thoughts ?

I'm trying to put some screensavers on my Kindle 4, but I must confess an absolute lack of knowledge in this area. I'm trying to follow the tutorials danar posted on the first page of this thread but I've not been able to get past the first step.

I've got Python, but after I type the first script to get a password I keep getting a syntax error "unexpected character after line continuation character". If anyone has any advice I'd appreciate it, it would be rewarding to do this myself, but I realise that dumbing it down to such a beginners level could be frustrating.

I might wait and see if the full jailbreak gets released at a later point. I can't wait to get rid of these utterly dull stock screensavers though.

hi there,
I just got kindle 4.0 and Id like to jailbreak it that I can use ankisrs software,
I dont really have a clue how to do it and dont even know what all these names mean and stuff,could anybody help and tell me how to fix my kindle?
thank you

You need to install usbnet, and you need to activate it, to see the kindle USB port as an "RNDIS" network adapter.

the solution was to unplug and reconnect the USB cable about a dozen times until it saw the device as a USB attached NIC. i updated to 4.0.1 and had to run the python script to get the password and now i'm in.

So does anyone know why this syntax error "unexpected character after line continuation character" keeps happening? If I can get past that I might be able to do the rest fine...

are you changing the serial to your device's serial? i simply copypasted the line and put in my serial and got my password right away. screwing up that line is easy - there are )) and " and ' quotes to mess with your eyes.

i have created the link and now have the screensavers folder, replete with some of the pictures from the zip that was posted here. when i bump the Kindle to to screensaver i get my same 4 ad screensavers.
